Specification of LettersiPiaitent; 1922,

Application filed December 14, 1920. Serial No. 430,650.

To all whom it may concern:

Be it known that I, ALFRED J. Mussnn, residing at Indiana, in the countyof Indiana and State of Pennsylvania, have invented new and usefulImprovements in Block Forms, of which the following is a specification.

This invention relates to moulds and has for an object the provision ofa mould for -making concrete building blocks, bricks and the like.

Another object is the provision of a block mould which is formed of anumber of units and which is so constructed that the number may bevaried as desired.

Another object is the provision of a mould which may be easily andquickly assembled for use, or disassembled for the removal of themoulded product.

A further object is the provision of a block mould which is of simpleand durable construction and which may be stored in a relatively smallspace when not in use.

With the above and other objects-in view,

the invention further includes the followstops or pillars 20 secured tothe platform 10.

ing novel features and details of construction, to be hereinafter morefully described, illustrated in the accompanying drawings and pointedout in the appended claims.

In the drawings Figure 1 is a plan view of a mould showing a number ofassembled units.

Figure 2 is an end view of the same.

Figure 8 is an enlarged plan showing a fragmentary portion of the mould.

Figure d is an enlarged transverse sectional view on the line 4-4 ofFigure 3.

Figure 5 is an enlarged fragmentary ,elevation of a portion of one ofthe metallic strips which form the sides of the mould.

Figure 6 is a detail perspective view of one of the end blocks.

Referring in detail to the drawings, like characters of reference denotecorresponding parts throughout the several views.

In carrying out the invention, the mould is preferably set up upon asmooth base,

herein shown as a platform 10, which platform may be equipped with agauge strip 11 for use in lining up the mould units.

These mould units include metallic strips or plates 12, whose ends abutthe gauge strip 11. The strips or plates 12 are spaced apart by endblocks 13, the latter being preferably constructed of wood and arrangedso as to provide elongated rectangular chambers 14 within which theblocks or bricks are formed.

The plates 12 and blocks 13 are connected to one another through themedium of bolts 15 and nuts 16, the said bolts being passed throughspaced openings 17 provided in the strips or plates 12 and having a head18 which extends from one face of the said strips or plates 12. The nut16 is positioned against the opposite face of the. plate or strip 12 sothat a projection is provided for each face of the plates or strips,which, in effect forms a bower. are, as before stated, arranged inspaced relation and are preferably disposed in horizontal pairs and areadapted to enter sockets 19 formed in the opposite ends of the endblocks 13, these sockets being properly spaced for this purpose. Themould units may thus be assembled with the ends of the plates or strips12 abutting the gauge strip 11 and the outer face of the outermost plateor strip resting against vertically arranged The plate or strip attheopposite end of the mould may be likewise secured.

It will be apparent from the foregoing description and the accompanyingdrawings, that the invention provides an exceedingly simple and durablemould which may The nuts and bolts be arranged in the number of unitsdesired for the moulding of blocks or bricks which may be readilydisassembled for storage or shipment.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right in herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed is 1. A mould comprisinga plurality of vertically disposed longitudinal strips spaced to providethe side walls of separate mould chambers, end walls removably locatedbe tween the strips, means detachably connecting the strips and endwalls and means for holding the outermost strips in position.

2. A mould comprising a plurality of vertically disposed longitudinalstrips spaced to provide the side walls of separate mould chambers, endwalls removably located between the strips, projections Carried by thestrips for engagement with sockets formed inthefledges of the end Wallsand means for holding the outermost strips'inposition.
